Selenium的基本使用有什么举例吗？

from selenium import webdriver

from selenium.webdriver.common.by import By

from selenium.webdriver.common.keys import Keys

from selenium.webdriver.support import expectedconditions as EC

from selenium.webdriver.support.wait import WebDriverWait

browser=webdriver.Chrome()
 try:

browser.get(https://www.baidu.com')

input =browser.find_element_by_id(kw)I 

input.send_keys('Python')

input.send_keys(Keys.ENTER)

wait=WebDriverWait(browser.10)

wait.until(EC.presence_of_elementlocated((ByIDcontent_left))) 

print(browser.current_url) 

print(browser.get_cookies()) 

print(browser.page_source) 

finally:

browser.close()
